What It Is: The Door Sensor / Paper Pickup Sensor (also sold as the Sensor PCB or PCA Label Circuit) - a small optical/mechanical sensor board that detects whether paper is loaded in the input tray and whether the top cover or ink-tank door is closed. A faulty sensor here causes a false 'out of paper' or 'open the cover/door' error even when paper is loaded and everything is closed properly.
Part Number: 3XV13-80037.
Condition: Refurbished Original / Pulled Original - professionally tested and working.
Warranty: 30-Day Replacement Warranty from date of delivery.

Note: This part number (3XV13-80037) is also stated on row 20's HP Smart Tank 515/516/530/419 paper sensor PCB listing - two different HP model families sharing one part number, worth the user double-checking before assuming interchangeability.
Note: This entire listing is a byte-for-byte duplicate of batch 23's Products_17.xlsx (identical title, description and image) - this whole upload (all 30 rows) matches batch 23 exactly, the first time an entire batch has turned out to be a 100% duplicate of the immediately preceding one. Reused batch 23's suggested content verbatim.
